I like the design of the city a lot, from the humble domes to the spires. But the best detail is the two flows of water from the top of a building, BRILLIANT! Would you mind if I used the picture on my blog, to visualize a city? (Credited back to you of course.)

Nice work on the atmosphere here, I like your sandy colours and the shape of the gate. I think the perspective on its arch is a bit off though, since our eyelevel is higher than the arch, we would not see so much of its underside. And try to avoid tensions like the line of the mountain running right through the background building's edge...there where the body of the building connects to the roof. But otherwise cool stuff Especially the hot sun glow on the ground really kick this off
